PANORAIVHC DISPLAY DEVICE.

SPECIFICATION forming part of Letters Patent No. 564,418, dated July 21, 1896.

Application led November 20, 1895. Serial No. 569,507. (No model.)

T0 all whom t may concern:

Be it known that I, LEVI lV. YAGGY, a citizen of the United States, and aresident of Lake Forest, in the county of' Lake and State of Illinois, have invented certain new and useful Improvements in Panoramic Display Devices,which are 'fully and clearly described in the following specification, and illustrated in the accompanying drawings, forming a part of this specification.

The invention V`relates to that class of devices of the character named which consist of a small case within which a scroll is carried by a pair of rollers and transferred from one to the other, passing across apertures in the case at which the pictures or other matter placed upon the scroll are eXhibited.

The object of the invention is to provide a portable device of this kind in which two series of pictures may be simultaneously exhibited without necessitating the use of two separate scrolls; and to this end the invention consists in so locating within a case or boX a series of rollers that a screen or scroll having pictures upon both of its sides may be carried thereby and exhibit one of its faces at one aperture inthe case and the other face at another aperture.

The invention consists in further minor details, the construction and arrangement of parts for the convenient supporting 0f the case and for covering the apertures.

In the accompanying drawings, Figure l is a front elevation of the device. Fig. 2 is a ver- -tical section on the line 2 2 of Fig.l.Y Fig. 3 is a detail of a portion of the device, drawn upon a larger scale. Fig. 4 isa front Velevation showing a modiedformof the front of the case. Fig. 5 is a plan section on the line 5 5 of Fig. 4, and Figs. 6 to 12 are details.

The case A is in the form of a thin boX, made of any suitable light material, preferably of wood. It is adapted to stand upon one of its edges, and the edge et, forming its bottom, and the edge ct', forming its top, are oblique to the front andv rear walls, so that when they are horizontal the case is inclined The lower portion B of the back of the case is openable, being hinged to the upper portion, as indicated at b, so that it may be thrown back to form a leg or support to hold the case in-its upright position.

A leaf C is pivotally attached at c to the face A of ther case near its bottom, and is of such size as to cover the entire upper portion of the face, and is adapted to be thrown downwardly so as to form a table or writing-desk. An arm D is rigidly secured to the leaf O so as to project inwardly from its hinged edge into the interior of the case A, and a rigid link d connects this arm with the movable portion B of the back of the case. The arm D is oset near its point of attachment to the leaf C, so that when the latter is closed against the front of the case the arm will lie along the inner surface thereof. The link connection between the arm D and the portion B of the back of the case serves to hold the latter in a closed position when the leaf is folded against the case and to open or throw back the leg B when the leaf is thrown downward.

The scroll or screen E is wound upon the rollers F F', journaled within the case, and may be transferred from one to the other of these rollers by means of a key e, adapted to fit within the end of either one of the rollers. The two rollers being alike in this respect, I have deemed it necessary to show in detail only one of them. The front A of the case is provided-with two apertures G G', across which the scroll E is adapted to travel. One of the rollers, as F, is located between these two apertures and the other, as F, is located at the outer side of one of them, as G. The scroll E is carried from the roller F across the other aperture, G, and turned backwardly over an idle-roller fat the opposite side thereof, and thence is carried to the roller F', crossing the aperture G and being held parallel with the front of the case by means of an idleroller f at the opposite or inner side of the aperture G. By this arrangement the opposite sides of the scroll are shown at the two apertures, and the pictures may be arranged ments, though my immediate purpose is to use it for the illustration of Bible subjects.

Should it be desired to exhibit the pictures 1 alternately, a leaf or screen may be used for covering one or both of theA apertures. As shown in Fig. 1, the apertures are arranged IOO in vertical order and are spaced apart a distance equal to the width of each. A pair of sliding screens or curtains H .I are employed for covering, respectively,the upper and lower aperture and are adapted to slide behind the strip A2, forming a portion of the front A of the case, for the purpose of uncovering the aperture. These screens or curtains are provided each with a small knob h j for their convenient manipulation.

As shown in Figs. et and 5, the apertures are arranged in horizontal alinement, and one of them is double the width of the other, and they are spaced apart by means of a strip equal in width to the width of the smaller aperture. A jointed leaf, whose extreme widthisequal to that of the larger aperture G, is hinged to the edge of? the separating-A strip A2 adjacent to this aperture, as indicated at m.

leafmay be folded against the strip A2 and leave both of the apertures open, or it may be open soas to cover by'itsouter portion M the smalleraperture G.

The size and arrangement of the apertures may be indefinitely varied, as may also the curtainsor leavesfor closing them, and I do notvtherefore desire to be limited to the exact construction shown.

The rollers F F are exactly alike, each being provided with one gudgeon F; F3, which passes entirely through the side of the case A. These gudgeons are provided each with an aperture p, extending in from its end to receive the key c, which is flat. The -inner endof each of these gudgeonsistransversely slotted, so as to forma neck Q, which is eccentric as to the body portion of the gudgeon and is of such size that the keyhole 2J cuts through its inner face. A tumbler R is pi voted to the inner surfacefof the side of the case A, which may be recessed for its reception, asindicated, and rests across the neck Q of the gudgeon. ThisA tumbler isfprovided with anoblique slot r, which opens to the median line` of the gudgeon and has its upper side rounded at itsmouth. This tumbler prevents the rotation of the roller Within which the key is inserted in one direction, leaving it free to move in theother direction and also `leaving it free to move in both directions when the key is not inserted, and

thereby admits of thel ready unrolling of the scroll by the turning of the roller carrying its oppositeV end, while preventingit from being carelessly turned backwardly so as to be unwound from the roller to which the key is applied. The action of this device is as follows: The key e, extending beyond the neck Q through the slot p, will pass the tumbler freely when turned in the direction of the movements of the hands ofa clock, reference The joint m of this leaf divides it into two equal `sections M M', so that the time into engagement therewith. When the movement is in the opposite direction, the key raises the tumbler by its first contact and enters the slot r, but its second contact is against the abrupt lower face of the slot, and further movement is thereby arrested. The outer end of the key e may be of any convenient form, it being necessary only that its body portion be flattened and its Width be such that it will certainly extend beyond the inner face of the neck Q.

Vhle I have shown the tumbler R in substantially the form of a hook, this shape is not essential to the proper performance of its functions, as it is only important that a shoulder be presented to the key as the lat* ter is turned in oneof its directions of'movement and thatno` shoulder or stop of any kind prevent the free' rotation of the key in the opposite direction.

I claim asmy invention-- l. The combination with a case, A, having a pair of apertures, as G and' G", inone of its sides, of a scroll Within the case and eX- tending from between the apertures across one of them, as G, and being folded backwardly and returning across the othern aperture, as G', and rollers, journaled within the case, for carrying `the scroll.
